1.A w14X74 of A992 Steel has a length of 20 feet and fixed ends. Compute the design compressive strength for LRFD and the allowable compressive strength for ASD.
2.What do the following terms mean for a soil? (Note: The question is asking for what the term means, not how the test is run)
a.) unconsolidated undrained
b.) consolidated undrained
c.) consolidated drained
3.Explain, in some detail, the design conditions and shear strengths used for each design condition when working with clay soils?
A beam must carry a total factored bending moment of 1062kN-m. It has a maximum beam effective depth of 25in. Design the beam in US customary units using f’c=4ksi and fy=413.4MPa. If necessary use d’=2.5in. Assume an exterior exposure according to AC..
a reinforced concrete beam with a section of 12 inches width and 24 inches depth is reinforced with 3no. 9 bars. fc'=5000psi and fy=60000psi. a 2 inch cover is used and the beam has a simply supported span lenght of 15ft.
A contractor is considering the purchase of an earthmover to avoid the cost of a rental unit. The earthmover costs $350,000 initially and will cost $7000 per year to store and maintain.
The selection of the runway for a given day is based on wind at the beginning of the day, and once selected will not be changed for the entire day. The airport has a single peak period each day; this is the hour between 4:00 and 5:00pm.
A rod was held on point B and the telescope is inclined so that the horizontal cross line of the transit intersects the rod at the 5.2 ft mark.If the reading on the vertical limb of the transit was +25° 19’, what was the difference in elevation betwe..
to apply shock loading to an artillery shell, a 20kg pendulum A is released from a know height and strikes impactor B at a known velocity v (theta). impactor B then strikes the 1 kg artillery shell C.
The compound interest formula is F=P(1+i)n where F is the total amount due, P is the initial cost or amount of money, i is the interest rate, and n is the number of periods interest is computed. 1.A student purchases a $1400 laptop computer for sc..

To satisfy desige limitation it is necessary to determine the effect of the 2- kN tension in the cable on the shear tension and bending of the fixed I-beam.
Name three types of metamorphic foliations, and draw a small sketch that shows a situation where a metamorphic foliation could cause problems in an excavation.
The following wind conditions are expected: V = 10 i - 5 j mph for 0 10 hr. Draw to scale the expected streakline of the stream for t = 3, 10, and 15 hr.
